Salivary Mucoceles in Children and Adolescents: A Clinicopathological Study
Article Sidebar
Main Article Content
Abstract
Background: Mucoceles are cavities filled with mucous and often occur in the oral mucosa. When they develop in children may cause diagnostic and management concerns.
Objectives: The aim of the present study was to examine retrospectively the clinical and pathological features of salivary mucoceles in children and adolescents.
Methods: 102 cases of salivary mucoceles in children and adolescents aged from 1 to 17 years were retrieved from our archives and examined for their clinical and histological features and frequency of recurrence. All cases were treated surgically under local anesthesia.
Results: Salivary mucoceles most often occurred in patients aged from 11 to 17 years (65,68%) with very weak male predominance (1,04/1). They were located most frequently in lower labial mucosa (87,25%). The incidence of extravasation mucoceles and mucous retention cysts were 99, 01% and 0,98% respectively. Confirmed history of local trauma and recurrence of the lesions were found 12,74% and 3,92% respectively. Histologically, 77.22% of cases of extravasation mucoceles were well-defined cysts surrounded by a capsule of granulation tissue and 22.77% granulation tissue intermixed with mucous. There was not relationship between the duration and histology of the mucous extravasation mucoceles.
Conclusions: Possibly, unnoticed local trauma and/or biting habit are the main etiological factors for the most frequent occurrence of extravasation mucoceles in the lower labial mucosa. The occurrence of mucous retention cysts and superficial mucoceles in children is very rare.
